20/40 foxwoods, basic checkup

[BigBadBabar]

one last hand for nina.

full table.

i raise a[img]/images/graemlins/heart.gif[/img]k[img]/images/graemlins/heart.gif[/img] in ep, first in, get 3bet by a normalish player whose 3bet range is pretty tight. he's not 3betting something like AT or 77 here for example.
all fold, i call.

flop AQ5 rainbow. how do you all tend to proceed here? we reckon that we're about 50/50 against his pfr 3bet range -- is that a fair assessment?

(babar's thinking: this could be standardy wa/wb like cc cc and bet riv?)
